Abstract: ABSTRACT OF THE DISCLOSURE:     The composition described herein is a hydrogenated polymer derived from a polybutadiene having originally between 95 and 100% 1,2-structure.  The hydrogenated product is an elastomeric material which is oxidation-resistant and stable against ozone.  Moreover, since the original high vinyl polymer may be made by a method which permits control of the molecular weight, the molecular weight of the ultimate hydro-genated products is also controllable.  The control of mole-cular weight and microstructure give highly desirable proper-ties in the ultimate elastomeric product, and also control of tacticity and crystallinity.

Abstract: ABSTRACT   A breech ring of a firearm, which can be closed and opened by a screw mechanism has conical threads which engage with corresponding threads on the screw. The threads of both the breech ring and the screw have non-threaded sectors arranged so that threaded sectors of the screw can be inserted into the non-threaded sectors of the ring and thereafter turned into engagement with the threads of the breech ring to secure the screw to the breach ring.  In the non-threaded sectors of the breech ring there are arranged spring plate retaining members which, together with a stripper, hold and center a bag charge or the like, behind a shell rammed into the firearm by a ramming unit.  The respective spring members are fastened at one end so that they protrude above the threaded sectors of the ring when the breech screw is in the open position and are then pushed down by the threaded sectors of the screw as it is closed onto the breech ring.

Abstract: LAMP CIRCUIT            ABSTRACT OF THE DISCLOSURE    To prolong the life of a deuterium gas discharge lamp and reduce photometric noise, a DC potential is applied between the cathode and the anode of the lamp to support the arc current through the tube and a separate AC potential is connected across the cathode through an AC amplitude control circuit that controls the amplitude of the AC current.  While the cathode is at room temper-ature, a potential proportional to the AC current through the cathode is balanced against a potential pro-portional to the AC potential drop across the cathode in an operational amplifier circuit and the output used to operate an indicating device. During operation of the lamp, the output of the operational amplifier circuit is used to control power applied to the cathode through the AC amplitude control circuit.  At this time, the pro-portionality factor for the AC potential drop is divided by a factor to cause  an increase in the AC current through the cathode and rebalance the operation-al amplifier circuit under lamp operating conditions at point where the cathode energy is just above an anomaly in the cathode-power cathode-temperature curve,

Abstract: ABSTRACT             In a process of producing cement, the ground raw material is de-acidified in a calcinator and is sub-sequently burnt in  a kiln and before being de-acidified in the calcinator is subjected to a multi-stage heat exchange with exhaust gas streams from the kiln and from the calcinator in two parallel series of heat exchange stages. The stream of ground raw material is delivered from heat exchange stages of each of said series to respective heat exchange stages of the other of said series. In order to improve the thermal efficiency and to reduce the equipment expenditure, the exhaust gas stream from the kiln is caused to deliver heat to the ground raw material in an additional heat exchange stage, which directly pre-cedes the calcinator in the flow path of the ground raw material, and the exhaust gas stream from the kiln is sub-sequently mixed with the exhaust gas stream from the calci-nator. The resulting stream of mixed exhaust gases is uni-formly distributed to the two series of heat exchange stages.
